MEASUREMENT OF PARTICLE DIMENSIONS IN COLLOIDAL SOLUTIONS USING THE CORRELATION SPECTROSCOPY TECHNIQUE
ABSTRAKT
The experimental setup which makes it possible to measure the time dependence of scattered light intensity from local concentration fluctuations of the Brownian particles in colloidal solutions is presented. The main attention is paid to the influence of frequency response parameters on the radii measurement accuracy of the scattering particles depending on their size at different signal/noise ratios. To reduce the measurement error in the range of 1 − 6 nm it is offered to use one-bit quantization method.
